I am up to page 64 of the assembly instructions for my K2 serial 7059. When performing the VCO Alignment, I started off with a reading of 8.2 volts. When adjusting L30 I got no changes at all, although the directions call for adjusting the slug until 6 volts is obtained.
Any help would be appreciated. Thanks, 73 de WN2K Paul Agoglia ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Paul,
The first thing to check is the DC voltage at RF Board U6 pin 5 - if it is not close to 4 volts, then you need to check the thermistor board for solder bridges. If the above checks OK, then try tuning downward fom 4000 kHz and see if the voltage drops. If it does, recount the red turns on T5 (OK, count the green ones too), you may have one too many turns - remove the extra turn and try again. If the voltage at the left end of R30 does not drop by the time you have tuned below 3500 kHz, then you will have to make some more measurements to localize the problem - tell us your results of the above tests and ask again. 73, Don W3FPR On 1/21/2011 1:07 PM, Paul Agoglia wrote: > I am up to page 64 of the assembly instructions for my K2 serial 7059.
